two gliders with the initial velocities and masses shown below hit each other in a perfectly elastic collision (elasticity 1.0). what will be the velocity of glider 2 after the collision?

Suppose you have a box. which of these is not necessarily a true statement regarding the relationship between the force applied to the box, the work done on the box, and the distance the box is moved? a. if the box is not moved, no force is being applied to the box. b. if no force is applied to the box, no work is done on the box. c. if work is done on the box, then a force is applied to the box. d. if work is done on the box, then the box is moved a distance.

The slope of a velocity time graph over any interval of time gives the during that interval

The strong nuclear force acts over a small distance than the electrostatic force. true or false
